The present invention relates to a class of fragrance precursor compounds comprising one or more of the compounds derived from the reaction of X&#x2014;OH and an aldehyde or ketone, the fragrance precursor compounds being of the formula X&#x2014;O&#x2014;C(R)(R*)(OR**) wherein R is a Calkyl group, a Caralkyl group or a Calkaryl group; R* is H or a Calkyl group, a Caralkyl group or a Calkaryl group; R** is H or X; X&#x2014;O representing a moiety derived from X&#x2014;OH, and wherein X&#x2014;OH is a compound selected from the group consisting of surfactants, fabric softeners, softener precursor ester amines, softener precursor amido amines, hair conditioners, skin conditions, saccharides and polymers. In a second aspect it relates to a method of preparing such precursors. Further the invention relates to compositions, comprising the precursor of the invention.

Functional fragrance precursor

The present invention relates to a class of fragrance precursor compounds comprising one or more of the compounds derived from the reaction of X&#x2014;OH and an aldehyde or ketone, the fragrance precursor compounds being of the formula X&#x2014;O&#x2014;C(R)(R*)(OR**) wherein R is a Calkyl group, a Caralkyl group or a Calkaryl group; R* is H or a Calkyl group, a Caralkyl group or a Calkaryl group; R** is H or X; X&#x2014;O representing a moiety derived from X&#x2014;OH, and wherein X&#x2014;OH is a compound selected from the group consisting of surfactants, fabric softeners, softener precursor ester amines, softener precursor amido amines, hair conditioners, skin conditions, saccharides and polymers. In a second aspect it relates to a method of preparing such precusors. Further the invention relates to compositions, comprising the precursor of the invention.

A fragrance precursor compound comprising one or more of the compounds derived from the reaction of X&#x2014;OH and an aldehyde or ketone, the fragrance precursor compounds being of the formula X&#x2014;O&#x2014;C(R)(R*)(R**) wherein R is a Calkyl group, a Caralkyl group or a Calkaryl group; R* is H or a Calkyl group, a Caralkyl group or a Calkaryl group; R** is O&#x2014;H or O&#x2014;X; O&#x2014;X representing a moiety derived from X&#x2014;OH, and wherein X&#x2014;OH is a material containing at least one hydroxyl group and having the following structure: 

A cleaning composition that contains film flakes with beneficial ingredients. The composition with the film flakes releases the beneficial ingredients when it is delivered to the target surface.
